Bhadelia is with Boston Medical Center and Boston University's National Emerging Infectious Disease Laboratories. She'll be doing the same kind of work as Dr. Kent Brantly, who was infected with Ebola in Liberia and returned to the United States Saturday, walking on his own from the ambulance into Emory University.

"I was so glad, not only to see him walking, but the fact that he's here and he's going to get the advanced supportive care that I think he should be getting," said Bhadelia.

Infected American relief worker Nancy Writebol will be coming home Tuesday, as well. The cases are raising worries in the U.S. about a potential outbreak.

Hospitals like Massachusetts General say they are prepared. Still, Dr. Paul Biddinger says the chances of an Ebola outbreak here are small, given that it's spread only by contact.

"There is a chance that this could spread because of how globalization of air travel and how fast people move around the globe is changing, but any one person is at very, very low risk," said Biddinger.

That's not be the case for Bhadelia. She'll be working in a country where they've declared a state of emergency and troops have been called in to quarantine victims.
